To all 'whom t may benoemd:

Be it known that I, FRANK THlLL, a citil zen of yLuxe'mbur and a resident of the city of New York, of Queens, in the county of Queensand State of New York, have inventeda new and Improved Spring Oiler, of which the following is a full, clear, and exact description.

This invention relates to spring oilers', an Object of the invention being to provide an apparatus which operates by air or other vanalogous fluid pressure to forcetheI leaves of the spring apart and hold the leaves spaced while oil, graphite, and the like is inj ected between. the leaves.

vA further object is to `provideoa device of .this character which utilizes a pressure of air and the like to properly position the device to separate the leaves of the spring and,

to maintain the leavesseparated while lubri-' cant, graphite and the like is forced between the leaves. f y

`With these and other objects in View, the invention consists in certainnovel features of construction and combinations and ar-y rangements of parts, which will be more. 'fully hereinafter cylinder'2 which is preferably integral with thel yoke. In this cylinder 2.a piston -3 is mounted and has a tubular piston rod 4 fixed thereto. ThisA tubular' rod 4 is movable through an opening 5 in the .yoke 1 and at its free end is shapedrto form a tapering wedge-like spring leaf spacer 6. This spacer l6 is in alinement with a fixed spacer 7 carried by thev free end of the yoke 1 so that when the spacer 6 is moved toward the spacer 7 they will force the leaves 8 of a leaf spring A apart, as clearly shown in Figure 1. y

A head 9 is screwed onto the outer end o f cylinder 2 and provided with a central openingelO to which the threaded end of an oil tu 11 inside of casing 2 is secured and registers with said opening 10.

This tube 11 projects through the piston 3v and telescopes in the tubular rod 4, and a ong Island City, borough 4packing gland or stuiiing box 12 is provided 1n the piston 3 to'make the juncture between )the tube 11 and the piston perfectly tight.

A 'coil spring 14is located in the casing 2 and interposed between the piston 3 and the \end ofthe casing 2 so'a's'to exert a rearward pressure on the piston.

A liquid 4supply pipe 15 vcommunicates with Athe opening 10 1n head 9 so as to discharge oil, graphite and the like throu h the tube, and a suitable valve 16 contro s the i 'iow through this pipe 15. Anairsupply .pipe 17 communicates with va passage 18 1n the head 9, and-this passage 18 discharges into the c linder 2 back of vpiston 3. A three-way valve 19 is provided in the pipe 17 which controls the iow of air into the casing, permits the exhaust of air from the casing and entirely shuts off the supply'of air at the will of the operator. This valve 19 may be made of standard type same in detail.

yThe piston rod 4 as above stated is of tubular form, the interior bore *of which is appreciably reduced at its forward end, forming a relatively small outlet passage 20 which discharges laterally through orifices 21 in the sides of the spacer 6.

admit oil, graphite and the like, which flows through the opening 10, tube 11, tubular piston rod 4 and passage 20 and is discharged through the outlet orifices 21 into the space between the leaves of the spring. To release the device, the valve 19 is turned so as to permit an'exhaust of air Vfrom cylinder 2 when the coil spring 14, will move the piston and its rod 4 rearwardly, thus withdrawing the spacers' from their position between the leaves of the spring.

Various sli ht changes and alterations might bema e in the general form of the arts described without departing from my invention, and hence Ido notl limit myself to the precise details set forth, but consider and hence it is not necessary to describe the i wardly.

myself at liberty to make such slight changes and alterations as fairly fall Wil-.hin the spirit and scope of the appended claims.

I claim:

1. A spring oiler, comprising a yoke, a casing fixed to one end of the yoke, a piston movable in the casing, a hollow rod ixed to the piston and projecting beyond thc end of the casing, a spacer xed to the yoke and in line with a spacer on the end of the rod, a lubricant supply tube projecting through the piston and into the tubular rod, a spring exerting pressure on the piston to move it rearwardly, and an air supply pipe communicating with the end of the casing whereby air when admitted will move the piston for- 2. A device of thecharacter described, comprising a yoke, a. casing fixed to one end of the yoke, a head on the outer end of the casing, a piston in the casing, a tubular rod fixed to the piston and projecting beyond the Wall ofthe yoke, spring leaf spacers carried by the rod and by the yoke and in alignment, the spacer carried by the rod havingdischarge orifices therein, an oil tube fixed to the head projecting through the pislonand sus telescoping in the rod, a spring in the easing exerting rearward pressure on the piston, an oilv supply pipe connected to the head and communicating with said tube, a vulve in said pipe, an air supply pipe communicatingr with a passage in the head andv adapted to discharge into the casing back of the piston, and a three-Way valve in saidlast-mentioned pipe.

FRANK THILL.
